Truly men say of Titus that he is clement and merciful, and therein differs much from Vespasian his father, and the clemency which he showed to the people of Gischala and other places which he has taken proves that is so…
-- G. A. Henty, For the Temple: A Tale of the Fall of Jerusalem, 1888
"Yet I am a clement man, Francesco, and sorely though that dog has wronged me by his silence, I thank Heaven for the grace to say—God rest his vile soul!"
-- Rafael Sabatini, Love-At-Arms, 1907
Clement came to English in the mid-1400s from the Latin word meaning "gentle, merciful."
